WINDOW-SHADE Application filed July 6,

My invention relates to clips for attaching pull cords to window shades.

Pull cords are ordinarily attached to the stick in the hem of a Windowshade by small I screw eyes. This method of attaching the pull cord isobjectionable because the lengthwise shifting of the stick in the hemmoves the screw and mars the hem so that it imparts a worn and unneatappearance to the shade and the screw is unhandy to attach and is oftenpulled out of the stick when pulling the shade by the cord. Many clipswere produced for attaching the pull cords but were unsatisfactorybecause they had teethorother projections which pierced the hem andpenetrated the stick to obtain a purchase. Due to the stick beingloosely inserted in the hem, a slight shifting of the stick or adownward pull of the cord would cause the projections to cut or tear thehem at the parts where they passed into the stick.

The objects of my invention are to provide a clip which will firmly holdthe pull cord to the hem and stick of a window shade withoutmarring thehem or injuring the stick and which is free of teeth or projections.

These objects, and other advantageous ends which will be describedhereinafter, I attain in the following manner, reference being had tothe accompanying drawing in which Figure 1 is a face view of a clip madein accordance with my invention illustrating it attached to a windowshade and a pull cord,

Figure 2 a section on line 2-2 of Figure 1,

Figure 3 a sect-ion on line 33 of F igure 1, illustrating the manner inwhich the clip is attached,

Fi ure 4 a vertical section through a modified form of the clip shown inFigure 2, and

Figure 5 a section on line 5-5 of- Figure 4.

Referring to the drawings, 1 indicates the hem of ashade, 2 the stick inthe hem, 3 my improved clip and 4 the pull cord of a tassel or ringattached to the clip. The clip is stamped from a piece of spring metaland bent into a. U-shape with the legs 5 of the U inclined toward eachother and of less length than the depth of the hem. An opening 6 ispunched in the bottom of the clip PULL-CORD CLIP.

1925. Serial No. 51,556.

through which cord 4 is passed and knotted inside of the clip. e sideedges 7 of the clip are preferably chamfered to prevent cutting the hemwhen attached.

In Figures 4 and 5, I have shown a. clip of modified form. It is'similarin all respects to the clip shown in Figures 1- -3, excepting theaddition of resiliency to the clip by securing a pair of spring strips 8within grooves 9 by rivets 10. I have "given the cor responding parts ofthis clip the reference characters of the preferred form with theexponent a.

To attach the clip to the hem, the stick is removed and the clip isslipped over the hem. The stick is thenpassed through the hem and forcedin between the inclined legs 5 of the clip to spring them apart from thedot-and-dash line position to the full line position shown in Figure 2.The end of the stick is preferably tapered as shown at 11 to facilitateits passage between the legs of the clip as shown in Figure 3.

The entire gripping faces of the clip bearing tightly against a largearea of the hem,

allows a clip of strong spring metal to be used without the danger ofinjuring the stick or marring the hem. A clip of strong spring metalwill, when attached in this manner, be under such tension that the legs5 of the U will firmly grip the hem and stick and hold the pull cord tothe shade under severe use.

While I have described my invention as taking a particular form, it willbe understood that tlie various parts may be changed without departingfrom the spirit thereof, and hence I do not limit myself to the preciseconstruction set forth, but consider that I am at liberty to make suchchanges and alterations as fairly come within the scope of the appendedclaim.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is i A clip of U-eross section provided withgrooves in a leg of the U, and spring strips secured within the grooves.

In testimony whereof I have signed my name to this specification.
